英文摘要	Octa-(4-tert-butylphenoxy) substituted naphthalocyanines coordinated with different central metals (Ga, In) were synthesized and their photophysical and optical limiting properties were investigated. The naphthalocyanines substituted peripherally with bulky groups have good solubility in organic solvents and the Q band absorption shows an obvious red shift to the near-IR region at about 800 nm. Studies on transient absorption spectra, photophysical parameters and optical limiting properties indicate that these compounds exhibit good optical limiting performance. The optical limiting thresholds of the naphthalocyanines are 0.26, 0.15 J cm(-2) for Gallium naphthalocyanines and Indium naphthalocyanines, respectively. The naphthalocyanines possess higher triplet state quantum yields (Phi(T)) and triplet-minus-ground state extinction coefficients (Delta epsilon(T)) than other simple phthalocyanines, which results in better optical limiting behaviour.
